Comparison between rest and stress right ventricular volumes and function. Top: scatter plots. The grey lines stand for the perfect identity (R, Pearson’s correlation; ccc, Lin’s concordance correlation coefficient). Bottom: Bland-Altman diagrams. The dashed lines indicate the mean difference (greyed is the 95% confidence interval) and the plain lines the 95% limits of agreement
